A chemical tanker truck crashes into a flooded, abandoned quarry (no soil or sediment on the bottom). It was carrying 1000 kg of benzene which is all released into the quarry and quickly becomes a completely mixed system. The quarry is 10 m deep and has a surface area of 10,000 m2. The quarry is fed by a spring with a constant temperature of 20°C and water flows out of it to a local stream at a flow rate of 10 m3/min. (a) How long will the concentration in the quarry violate the applicable NJ Surface Water Quality Standards (FW2) (assume only loss is flow out)? (b) If bacteria is introduced to the quarry that can consume benzene following a 1st order decay process with a decay constant k = 0.01 day-1, how long will the concentration in the quarry violate the regulations?
A lake has 5×10^9 m³ of water with a DO concentration of 7.5 mg/l. 12000 m³ of an effluent with 120 mg/l BOD is discharged into this lake and 70% of the organic matter is decomposed in 7 days. Find out the DO concentration in the lake after 7 days.
You are the lead engineer on a wastewater treatment plant with a biological reactor. You are required todetermine how much biomass will be produced in kg per day in your plant. A junior engineer determines theultimate BOD of the incoming waste as 600 mg/l, with a decay constant of 0.1/d. The incoming substrateconcentration used should be the five-day BOD. The incoming flow is 75 m3/d however there are lossesupstream of the plant accounting for 15 m3/d of the flow. The target BOD discharged from the plant is 25mg/l. the kinetic constants for the system are Ks = 90 mg/L BOD5, kd = 0.2 d-1, μm = 1.5 d-1, and Y = 0.6 mg VSS/mgBOD5. Include a sketch to illustrate the biological reactor and its incoming flows.
A stream containing no biochemical O2 demand (obviously a hypothetical situation) has a DO of 5.00 mg/L and a flow rate of 8.70 m3/s. The temperature of the stream is 15 degrees Celsius. The average velocity in the stream is 0.174 m/s. The average depth is 5 m. Determine the reaeration coefficient and the rate of reaeration.
The flow of a river is 1.5 m3/s, the river is polluted with the pesticide permethrin and flows into a lake (100 m x 100 m 2.5 m) 25000m3. Steady state concentration of permethrin leaving the lake is 1.4 ppm and the average cross-sectional area of the river is 2.7 m2. The half-life of permethrin in this environment is 19 hrs.
A lake with a constant volume of 10 x 10^6m^3 is fed by a pollution-free stream with a flow rate of 50 m^3/s. A factory discharges 5 m^3/s of a non conservative waste with a concentration of 100 mg/L into the lake. The pollution has a reaction rate coefficient K of 0.35/day. Assuming the pollution is well mixed in the lake, find the steady-state concentration of the pollution in the lake.

A small lake with volume 10,000 m3 has a stream flowing into it with flow rate 100 m3/day and a Toluene concentration of 1.0 mg/m3. A factory discharges 5 m3/day into the lake with Toluene concentration of 10 mg/m3 – they want to increase effluent to 50 mg/m3. Toluene decays at a rate of 0.01/day. Assume steady-state and completely mixed (CSTR). a) How would this increase in discharge concentration change the lake concentration? b) Field studies show that the same lake would be better represented by dividing the lake into two cells. The first cell having a volume of 2,500 m3 and the second with 7,500 m3. How does this affect the estimate of concentration leaving the lake? Compare with one-cell model.Assume the factory continues to discharge at 10 mg/m3 into the first cell.c) Why does modeling the lake as multiple cells impact the final concentration leaving the lake? What do you expect might happen to the final concentration leaving the lake if we modeled it as more cells? How would…
Plateau Creek in Colorado carries 10 m3/s of water with a Selenium (Se) concentration of 0.003 mg/L. A farmer starts withdrawing 2 m3/s of the creek water to irrigate his land. During irrigation, the water picks up Se from the salts in the soil. One third of the irrigation water is lostto the ground and plants, and the other two-thirds is returned back to Plateau Creek. The irrigation run-off back to the creek contains 1.5 mg/L Se. Se is a conservative, non-reactive substance, and the stream does not pick up more Se from any other source. If the farmer irrigatescontinuously, what will be the steady-state concentration of Se in Plateau Creek, downstream from the farm (after the irrigation run-off returns to the Creek)?
